Where are the schematics for the AD5380 IQ Demodulator evaluation board? I see some in the data sheet, but these are for an older (or newer) revision than what I've got.
In particular, the single ended interface is gone, but the baluns are still there. Also, there's an undefined switch on the board, as well as two terminals (GND1 and ?...presumably Vadj) I'd like to know about.
The AD5380 is a 14-bit, 40-channel DAC. Can you check the part number?
Sorry, ADL5380. Board in question is the ADL5380-EVALZ.
The schematics and BOM for the ADL5380-EVALZ evaluation board can now be downloaded from the product webpage:

I tried to post it up here, but the tool won't let me. That should provide you with the latest documentation.
